## Prosecution of Crimes Against Humanity

Crimes against humanity encompass various criminal acts that are particularly egregious in nature and are usually committed as part of a widespread or systematic attack directed against any civilian population. Significant developments in international law have aimed to ensure that those responsible for such crimes face justice. In the complex framework of international and national jurisdictions, different entities play a role in prosecuting these offenses.

### International Prosecution Bodies

#### International Criminal Court (ICC)
The International Criminal Court, established by the Rome Statute in 2002, plays a pivotal role in addressing serious atrocities that trouble the international community, including genocide, war crimes, and crimes against humanity. The ICC is intended as a court of last resort, stepping in only when national courts are unwilling or unable to prosecute criminals. It has the authority to prosecute individuals and holds them accountable for crimes committed after 2002 that fall within its jurisdiction.

#### Ad Hoc Tribunals
Historically, ad hoc tribunals have also played significant roles in the prosecution of crimes against humanity. Notable examples include the Nuremberg Trials after World War II and the International Criminal Tribunals for the former Yugoslavia (ICTY) and Rwanda (ICTR). These tribunals were established in response to specific conflicts and have jurisdiction over crimes committed within a defined time frame and region.

### National Prosecution

#### General Role
At the national level, entities responsible for initiating legal proceedings against crimes typically associated with local or national instances include titles such as district attorney, county attorney, state's attorney, or public prosecutors, depending on the jurisdiction. While these titles and roles may vary significantly from one country to another, their fundamental purpose is to conduct prosecutions on behalf of the government.

#### District Attorney, County Attorney, and State's Attorney
In the United States, for example, district attorneys (DAs) are elected officials who represent the government in the prosecution of criminal offenses within a specific district. Similarly, county attorneys operate within specific counties, and state attorneys general may have overarching jurisdiction that includes handling certain high-profile cases at the state level. While their primary focus is typically on domestic law, these prosecutors can also become involved in cases of crimes against humanity if those crimes occur within their jurisdiction and involve violations of state or federal law.

### Legal Framework and Challenges
Prosecuting crimes against humanity under national laws can be challenging. These types of crimes often require navigation through complexities not typically encountered in conventional criminal law, including issues of command responsibility, mass atrocity, and large-scale human rights abuses. Most countries have specific legislation that incorporates international law into domestic law, enabling the prosecution of such severe crimes.

National courts can also extend their typically domestic focus to include international crimes under the principle of universal jurisdiction. This principle allows national courts to prosecute individuals for serious international crimes such as crimes against humanity, regardless of where the crime was committed, and irrespective of the accused’s nationality or the victims’ nationality.

### Conclusion
The responsibility for prosecuting crimes against humanity is shared between various legal entities and jurisdictions, each playing a critical role depending on the nature, location, and specifics of the crime. From international bodies like the ICC to local prosecutors such as district or county attorneys, the legal framework designed to address these heinous crimes is multilayered and aimed at ensuring accountability, justice, and deterrence. As the global landscape evolves, so too does the approach to prosecuting these grave offenses, continually adapting to meet the demands of justice across the world.
